UV Resistant Marine Grade EPOXY Resin (3 Gallon Kit) * Clear * Non-Toxic * Boat * BAR TOP * Table TOP * Fiberglass * Wood * Laminating

Just used the 3 gallon kit to coat the bottom of a skiff boat i am building. My only complaint is that I should have order more because i ran out. The product is great far as mixing and application. I used a cheap 1 dollar plastic kitchen measuring cup to measure 600mL of resin to 300 mL of hardener. It was easy to know when it was mixed well as it turned from cloudy to clear and was about the consistency of corn syrup. After 24 hours of set up it's dry and hard as a rock. it was easy to apply to the 10 oz fiberglass cloth and penetrated it well for a good bond to the wood. I applied it outside and did not notice any major issue with smell as epoxies are known to have, though i am sure in a closed environment of a garage there would be a some smell. For the price i am very happy with the result and i will be purchasing more to complete the process and apply more coats on what i have done.Update: It's 2019 now and the boat has been outside the entire time. The paint applied over the epoxy was oil based exterior and it has not flaked off or discolored at all due to the epoxy. I am planning, when i get money to buy another batch and do the entire interior as well. This is good epoxy for the money. My suggestion though if you are using it to waterproof a wood boat, cut the mixture down with about 100 mL of acetone so the first coat is thinner. This allows for a greater penetration of the epoxy into the wood. Later coats can be regular mix as stated on the bottle.

My daughter and I built a dory boat with this epoxy. Used more than I thought we would need - should have bought the 3 gallon kit right off. But I have some left over now. I'm impressed with this epoxy. For the cost it's pretty good. Sets up hard after 24 - 36 hours. It's very temp sensitive. If your workspace gets much below 70 it really slows down in my observation. I used it for laminations, glass, barrier coats, thinned it for a penetrating effect, and thickened it for fillets. It performed everything well. (Yes I know the debate about modifying epoxy... whatever) My previous point of reference was the inexpensive resins and fillers from body kits and the like - this is much better. This wets out the fabric much better. Probably not as good as West System or any of the other "real" boat epoxies but then again it's much less expensive and if you're just learning and you lose a batch you don't have to be sad.FYI wear a mask. This stuff stinks. It doesn't blush either so I applied coat over coat with no sanding and had no ill effects. It stuck like glue! ;)

I ordered the 3 gallon kit to cover two tables that I had previous covered with GlazeCoat (an indoor epoxy sold at Lowes) because I want to put these tables outside in the sun. The Glaze Coat indoor epoxy had hazed and oxidized in the window sunlight so I covered with this outdoor epoxy and the hazing cleared immediately. The instructions for this epoxy are incorrect or incomplete in my opinion. It's better to follow the instructions that GlazeCoat provide, being that you should mix in one bucket, pour into another bucket, continue mixing, and then pour. This epoxy’s instructions say it's fine to mix in one bucket, but trust me you don't want to do that because the edges of the first bucket don't mix well. After I'm done with this project the first bucket is sticky, but my second bucket is rock hard. You don't want that poorly mixed stick epoxy mixed in with your properly mixed rock hard epoxy or your surface will have sticky spots. I love how there's no fumes from this epoxy. It smells like liquorish which is pleasant compared to the alternative chemical smell of other epoxies. Use a plumber's torch to remove bubbles after pouring and spreading on your surface. You WILL have bubbles so you need to do this step. I'm not sure why this is not stated in the instructions like in the Glazecoat instructions. I covered the first table in the day time at about 80 degrees. It has a workability time of 30 minutes as the instruction say. 35 min is starts getting hot and smoking in your mixing bucket if you try moving it (which I think is the underlining issue of the problem I had covering the second table - pics attached). If you're covering a table and let the epoxy drip off the edge, MAKE SURE you spread it thin (no more than 3/16" thick), because thicker than that it’s still moving and dripping off the edge after 35 minutes and you will have hazing and an alligator skin look because it gets hot when it's moving at this time limit. LUCKILY I spread this epoxy to this thickness on my first (and most expensive) table, so it cured clear and beautiful. The second table I just wanted to use all the epoxy I had left over and probably spread the epoxy to a thickness of 1/4"-5/16" thickness for it do just level itself out and drip over the edge. Well this thickness, coupled with it's viscosity and gravity, the epoxy was still dripping off the edge well after an hour after first pouring and while it was trying to cure... so horrible hazing and alligatoring occurred as seen in the picture. I also did this table in the evening and it was considerably more humid, so maybe the heat from curing coupled with the cool night air and humidity caused condensation occur on the top skin and caused the haze spots and alligator skin look. After about 4 hours you can begin to touch the epoxy without it sticking. After a couple days it becomes fairly durable for moving it. I'd probably wait a week before normal use. If you follow these instructions you will be very happy with this product. I'm hoping a wax and buffing will remove the haze spots on the second table. I'll update this review in a couple months after I see how this epoxy performs out in the sun.Update: after two years I can tell you that buffing did not get rid of the hazing and alligator skin look on the second table. I am attaching a 3rd pic showing you what it looks like now after normal exposure to all seasons of extreme heat and cold. It has not yellowed, but is it very hazy and tons of micro cracks. You can tell the difference in the pic between the area that has remained covered and the area exposed to the weather.

We just completed covering a 300 sq ft deck with a layup of 25oz cloth and 12 gallons of this Res Tech epoxy. Mixing was done using 3/4 of a gallon at a time with an electric drill mounted stir wand. We mixed indoor on room temperature product and applied it outdoor on a 60F deck. Application was straightforward and the viscosity was perfect, not to thick and not too runny. As far a cure time good this stuff definitely is a lot slower than the West System and it was greatly appreciated that it was slower. However, after 24 hours we could walk on it. We were able to add some space heaters on the side but it was outside and it was 50F overnight.By the way FedEx lost the 5 gallon bucket of hardener twice and Scott at Res Tech finally sent a third shipment of hardener over night at their cost. Thanks :)

Item was advertised as a gallon of epoxy, and a gallon of hardener, it did not say less than half a gallon on one and a quarter of a gallon on the other. What I received was less than half a gallon of epoxy, and approx two pints of hardener. I paid 90 some odd dollars for this and I demand my money back or a full shipment of what was missing.
